SPECIFICATION forming part of Letters Patent No. 763,675, dated June 2 8, 190%. Application filed April 25,1902. Serial No. 104,704. (llo specimens.)

To all volume it may concern:

Be it known that l, WAssILiY KInssANoFr, a subject of the Czar of Russia, residing at Taganrog, in the Empire of Russia, have invented new and useful Improvements in Explosives, of which the following is a specification.

The explosive forming the subject of the present invention consists of two parts-via, a dry pulverulent mixture and a fluid mixture, which are prepared separately and forwarded to the work-place, where they are then brought together. The dry constituent is a mechanical mixture, consisting of finely-ground slightly-pressed powder of chlorate and permanganate of potassium and is filled into cartridge-cases of ordinary cotton-packing paper. The constituents of the cartridges are: potassium chlorate, (K0103) seventy per cent. ;..potassium permanganate, (KMnO twenty per cent; total, ninety per cent. parts, by weight. The second constituent is turpentine-phenol oil, which is a liquid consisting of turpentineoil to which carbolic acid is added. The oil is poured into tin boxes of various sizes and soldered up. Constituents of the oil: turpentine, (0101110,) nine per cent. carbolic acid, (GGI 16(),) one per cent; total, ten per cent. parts, by weight.

The. explosive manufactured as above set forth possesses the following characteristics:

First. The dry cartridges submitted to a heavy blow between hammer and anvil do not explode. If the ground powder is ignited with a match, it does not burn. Brought in contact with burning objects it-slightly intensifies the combustion; but the latter ceases at once immediately the said burning object is extinguished or burned up. Through the explosion of the capsule with fulminate of mercury the dry cartridge does not explode, nor will it be ignited. It will merely be scattered by the force due to the explosion of the capsule.

Second. If the'turpentine-phenol oil is ignited, it burns quietly, without exploding, with a black smoky flame. Should the capsules with fulminate of mercury explode in the tins of oil, the latter does not explode, nor does it become ignited.

lharacteristics of the explosive when its two constituents are mixed together are as follows, when ninety parts, by weight, of the dry cartridges are impregnated with ten parts, by weight, of oil: On ignition the cartridges burn brilliantly like Bengal light, but without explosion. Submitted to a blow between two steel surfaces or to a blow with an iron rod in a stone blast-hole, they do not explode if only small sparks are caused. The

cartridges can be exploded by simultaneous action of blow and spark, which can be eiiected lay-exploding the cartridges in the capsule with fulminate of mercury. The cartridge with the new explosive does not explode entirely in the open air under application of a capsule. in a closed space, however, (a hole in stone, the empty part being filled up with sand or water,) all the cartridges will explode completely.

The following formulae show the composition of the explosive mixed as above described: potassium chlorate, (K0103) seventy per cent; potassium permanganate, (KMnO twenty per cent. total, pulverulent part, ninety per cent; turpentine, (Cal-116,) nine per cent; carbolic acid, (UGHGOJ one per cent.; total, liquid part, ten per cent.

The proportion existing between. the reacting substances causes perfect combustion of.

the same in a closed space.

' Having thus described my invention, what I. claim as new, and desire to secure by Letters Patent, is-

An explosive consisting of the following constituents: potassium chlorate, (1810103,) seventy per cent; potassium permanganate, (KMnOi,) twenty per cent; total, ninety parts, by weight; turpentine, (CwHm,) nine per cent.; carbolic acid. (C('1H(U,) one per cent.; total, ten parts, by weight.

In testimony whereof i. have signed this specification in the presence of two subscribing witnesses.
